                    Spring Session是一个用于在分布式系统中管理会话的解决方案。它的主要作用是解决在分布式环境下会话管理的问题，确保用户在多个服务器上访问应用程序时，能够持续保持会话状态。
                </p>
                <p class="mt-6">
                    常见的Web应用程序通常使用Session来跟踪用户的登录状态和其他会话信息。在单机环境下，这是很容易实现的，但在分布式系统中，由于每个请求可能被不同的服务器处理，会话数据无法简单地存储在本地内存中，导致会话不连续或丢失的问题。
